exemplars

Just been reading the exemplars for internally assessed AS on the NZQA
website.


http://www.nzqa.govt.nz/ncea/resources/physics/exemplars.html

They have really clarified a number of points for me just as we are coming
into our major assessment time. A great resource that I recommend everyone
reads.

One tiny point I saw which I'm unsure of though was in the level 2
measurement

Student # 5
Grade: Merit / Excellence
Thickness of 10 pages = 2 mm. Therefore thickness of 1 page = 0.20 mm. 
Appropriate use of significant figures.


I thought that dividing by 10 did not change the number of sf but just
increased the number of dp. Answer 0.2mm, same sf, extra dp.

What do the rest of you teach?
